Resolution Force 1X

Our thoroughly modern Resolution2 frameset, designed for multi-surface, all-season adventures at speed and in comfort, matched up with the iconic Force 1X drivetrain.

We've been super impressed with the performance of the 1X systems on ourBokehAdventureSport bikes and this got us really interested in the benefits of using these systems on our SE4SON/Multi-Surface/Ultra-Endurance road bikes. The benefits in efficiency, low maintenance, low weight and simplicity make it ideally suited to the Resolution's supreme steel ride.

Halving the number of chainrings doesn’t halve the number of usable gears. It doesn’t have to mean massive jumps in pedalling rhythm either. The entire range of gears accessible from one hand, utilising the responsive actuation and positive lever feel from SRAM's 'Double-tap' technology. 1X setups don’t drop chains in rougher situations like double/triple ones can which means you can travel faster & further over rougher surfaces with confidence and less down-time.

Advanced materials such as carbon fibre used in crank arms, shifters and rear-mech give incredibly positive and precise shifting coupled with minimal power loss. This translates into maximum output at the rear wheel and fuss-free mileage where you can forget the bike and immerse yourself in the adventure.

Large volume Schwalbe tyres designed for maximum speed, ride quality and all-surface control. Supplied with tubes but can be set-up tubeless.

Clearance for full mudguards with 30mm tyres.

Specially developed, Mason x Hunt disc-specific wheel set.

Fully and discretely eyeletted for rack and ‘guards.

Unique Mason MultiPort adaptable internal routing.

UK designed, Carbon rail Fabric Scoop Pro saddle.

Carbon Mason Penta microadjust post and Mason Macro clamp.

Our frame sets deserve the best components, so we put a great deal of thought into the mix of parts used for each bike build. Bars, stem and crankset are sized to match frame size choice, but we can sometimes make sizing adjustments at your request.

We'll set-up the front brake to be operated by the Right Hand lever for all UK destinations. For destinations outside of the UK, we'll set-up your bicycle with Front Brake/Left Hand as standard. It's no problem for us to set-up the brakes in your own chosen configuration, please state in 'Order Notes' how you like 'em.

This page gives you some guidelines based on height, but these are only a starting point for a proper bike fitting. The dimensions show the extremes of useable frame size based on height.

Fitting a bike to a rider is an important process, this information is a start to the process but it’s not really possible to give 100% accurate fitting instructions online.

Humans are odd shapes, each person’s physical dimensions: arm, torso, femur length, level of flexibility even skill level are very different. This means that there will invariably be different frame size requirements, even for people of the same height and inseam.

We are experienced in sizing and geometry, so of course we will be on the end of the phone or email to help and advise, but I would always recommend having a proper bike fit done before committing, especially if you feel like you may be between sizes.

We have specified bar width, stem length, and crank length to be the best fit for the majority of riders on each frame size, but we can sometimes make adjustments to this at your request. Please contact us for advice, or just let us know your sizing requirements in the comments box at the checkout page.

If you are between sizes, it’s probably best to go with the smaller size. It’s easier to make a smaller frame fit a little larger than vice versa.

Multiport

Unique to MASON. Our frames use an adaptable, internal cable routing system. Developed by us to allow your Mason frame to be used with a combination of control systems and adapt and evolve with your requirements and riding styles. We are the first to bring this type of system to a performance steel frame. Interchangeable alloy parts allow five options:

Taper Head Tubes

The large overall diameter provides a useful weld area. The fully integrated headset is light and has a very low stack-height. Large 1.5” lower bearing, mated to a tapered carbon fork steerer, spreads the load and gives flex-free braking and instant response to steering input.

Threaded Bottom Brackets

We choose a more traditional 68mm, BSA, threaded standard for our AdventureSport frames because we believe it gives greater durability and creak-free reliability over many miles. The threaded BB is easier to service using standard tools and you are more likely to find a replacement when adventuring far from home. A properly lubricated, threaded BB is also an ideal interface with a metal BB shell.

Hourglass Stays

We tried many shapes before settling on this one, the wall thickness tapers from top to base and the perfect ‘hourglass’ profile gives a sublime, smooth ride with the added spring of steel keeping things lively. We add a custom bend at the base to work with the disc-rotor and calliper.

F-Stop Axle System

The Mason F-Stop Insert System was developed for our exclusive Aperture2 fork, used on our Definition, Resolution and Aspect bicycles.

The axle uses our 12mm Thru-Axle 'SwitchLever' which features a removable CNCd lever key, fitted with a 6mm hex key. You can leave the key in and it's there for easy wheel removal, or take it off and leave it in your pocket for a clean dropout.

The Aperture2 fork also features removable tip inserts meaning that all wearing parts are replaceable, vastly extending the life of your Mason bicycle.

Columbus Tubing

This frame is constructed from a unique blend of Columbus Spirit and Life tubing. Hand Selected, custom shaped, seamless, progressive butted, fine grain, niobium doped and joined with perfect Tig welds.

27.2 Seat Post

Our oversize seat tubes don't house oversize seat posts. The large diameter seat tube helps the 'core-stability' of the frame but large, stiff seat posts don't help rider comfort. A 27.2mm post helps to dial out road-buzz and the smoother ride means you stay fresher for longer.

Disc Brakes

This frame is designed for disc brakes. They work consistently in all conditions, pull up quicker in the wet, they don't grind your expensive rims into black sludge and in my experience they change the whole riding experience for the better, especially when coupled with modern disc-specific wheels and high-volume tyres. You’ll find yourself riding in a more confident, controlled, fluid and ultimately more efficient way.

Internal Routing

The cables, hoses and electronic shift control wires run through the frame tubes, guided by our Mason 'MultiPort' adaptable inserts. Interchangeable Internal routing keeps the control cabling away from road dirt and grime, helps avoid accidental damage, makes cleaning easy, de-clutters your bike and means you can adapt your bike easily to work with various shifting and braking methods. For adventure and endurance riding, internal routing also has the advatage that it is easy to strap frame packs to the frame tubes without being hindered by external cabling and hoses.

Integrated Headset

The headset drops into a tapered seat in the head tube and is tensioned using a headset tensioner within the fork steerer. Tensioning the headset centres it on the taper and prevents any play. The larger lower bearing allows a tapered steerer and larger crown. This gives sharper response, helps reduce flex under braking and spreads bearing load.

1x Drivetrain

'1x' is a multi-terrain performance drivetrain with maximum chain security thanks to the narrow-wide chainring and jockey wheels and 'clutched' rear-mech. The range of gears is equivalent to a 2x compact drivetrain, but with the elimination of doubled-up crossover gears. '1x' are lighter, quieter, and more secure.

ISO Testing

All our frames complete the intensive strength and fatigue testing to fully comply with ISO standards. The AdventureSport range of frames are put through the tough road race ISO testing, with its brutal Horizontal Fatigue test. The Parallax fork goes through the MTB test with it's even tougher 'Drop Testing' standards. Because of this we are confident that these frames will last you a lifetime of hard riding.

It's not law that frames and forks have to be tested to their limits like this, but our frames will always be tested in this way, so you can be sure that your MASON frame not only looks beautiful with a ride quality to match, but it is tough, safe and dependable too.

FlatMount Brake Calipers

Flat mount disc-brake callipers are lighter, neater, and open up more space within the dropout area for racks and ‘guards. The calliper is mounted to the dropout, allowing us to use a lighter, more comfortable seat-stay. Up front, the calliper is mounted directly to the fork [via the brake manufacturers adaptor] and offers a cleaner and more minimalist appearance and also provides a compact packaging of the brake caliper.

Thru-Axle Front & Rear

Our Steel and Alu. frames use the Mason ‘F-Stop’ thru-axles up front and bolt-thru axles at the rear. Our Titanium frames use the F-Stop axles front & Rear.

The F-Stop system is clockable to your desired position and can be adjusted as it 'beds-in', giving you a 'tool-free' and serviceable thru-axle with a familiar QR-style lever locking system. Threads are replaceable if damaged.

Essential Dimensions: Resolution/Definition

BRAKING

Resolution Rotor Size: The fork can take a Ø140 or Ø160mm rotor [using adaptor], if you are using Shimano IceTech rotors then Ø140mm rotors either end are fine in normal use, although Shimano recommend Ø160 both ends for larger riders or extended long descents, especially when loaded. SRAM recommend Ø160mm front/rear. A Ø160mm up front is best if you are using cable braking. The Resolution2, with Thru-Axle front & rear will now accept a Ø160mm rotor on the rear. [140mm is the maximum recommended diameter for the V1 rear].

Resolution Caliper Type: Frames are fitted with the Flat-Mount front & rear (adaptable to post-mount with correct adapter). There are no clearance issues with modern Shimano or SRAM hydraulic systems or mechanical systems such as ‘TRP Spyre’. Some bulky systems like the ‘TRP HyRd’ may have compatibility issues on smaller size frames. Please contact us for advice if you are in doubt.

Definition Rotor Size: The fork can take a Ø140 or Ø160mm rotor [using adaptor], if you are using Shimano IceTech rotors then Ø140mm rotors either end are fine in normal use, although Shimano recommend Ø160 both ends for larger riders or extended long descents, especially when loaded. SRAM recommend Ø160mm front/rear. A Ø160mm up front is best if you are using cable braking. 160mm is the maximum recommended diameter for the rear.

Definition Caliper Type: Frames are fitted with the flat-mount front and flat-mount rear. There are no clearance issues with modern Shimano systems or mechanical systems such as ‘TRP Spyre’. Some bulky systems like the ‘TRP HyRd’ may have compatibility issues on smaller size frames.

NOTE: Our frames are compatible with most modern disc-brake systems but may not be suitable for ALL brake callipers. Please check clearance before purchasing your braking system.
